I made a product with a tagline "Turnkey monetization for API developers"

When a developer creates an API, in order to make it paid, there's still quite a bit of work ahead.

User registration, authentication, subscription management, subscription plans, limit enforcement, premium features, usage metering, billing, invoicing, payment collection… — in many cases that's more effort than developing the API itself.

The product in the video provides all these features and requires no integration.
The developer needs to click several buttons to configure the API product and get a checkout link which then can be used for a Big Red Subscribe Button™ on a landing page.

When users click the checkout button, they are taken to the self-service onboarding portal where they can subscribe to the API, pay and start using it.

The video:

The time needed to start selling APIs with this product is reduced by a lot.
Isn't it better to spend that time on marketing or developing another commercial API?

What do you think?
